The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

This paper investigates grinding of mineral mixtures with different grindabilities in the Bond ball mill. Understanding the ore mixture grinding is of great importance in mineral processing. The energy required for crushing and grinding is presented by the Bond work index and is determined by means of Bond grindability test. This paper presents the experimental results of the Bond work index ...

Bond Ball Miningandmetallurgy. The Bond ball mill work index is one of the most commonly used grindability tests in mining, and is often referred to as the Bond work index.. The test is a 'locked-cycle' test where ground product is removed from test cycles and replaced by fresh feed. Get Price

Aside from the bond strength reading, the operator must also record the bond failure mode. Failure mode in this context refers to one of the following: 1) first bond (ball bond) lifting; 2) neck break; 3) midspan wire break; 4) heel break; and 5) second bond (wedge bond) lifting.

The Bond Ball Mill Grindability Test is a locked-cycle laboratory grinding test. It provides the Bond Ball Mill Work Index which expresses the resistance of a material to ball milling. This Index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required for grinding, and for ball mill scale-up.

Ball bonding requires only three axes of movement (X,Y,Z) while wedge bonding requires four axes of movement (X,Y,Z,θ). In ball bonding, only gold (Au) wire can be used while gold and aluminum (Al) wires are used commonly in wedge bonding. This is because Al wire will oxidize during the electronic flame off (EFO) process to form the ball. The ...
